Embodiment Construction

[0048]Referring to FIG. 1A, the disclosed designs for electrodes, leads, and other energy delivery elements may be part of a system 100 which includes a housing 112 containing the necessary pulse generator and associated electronics, circuitry, battery and related components and at least one lead 10 carrying some or all of the electrodes or other energy delivery elements needed to deliver electrical energy to target nervous system structures. In the illustrated embodiment, the housing 112 is positioned in the inferior vena cava (“IVC”), but it may alternatively be positioned in other vessels including, but not limited to, the superior vena cava (“SVC”), or the left or right subclavian vein (“LSV” or “RSV”). An anchor 116 is used to retain the housing within the vasculature. Features suitable for use with the system, including embodiments of leads, electrodes, housings and anchors are shown and described in the following patents and applications, each of which is incorporated herein ...

Abstract

An intravascular lead is used to deliver energy for stimulating nervous system targets using energy delivery elements (e.g. electrodes) that are in direct contact with the nervous system targets. The lead may be positioned within the internal jugular vein and the nervous system targets may include the carotid artery/carotid sinus bulb and/or associated baroreceptor afferents, and/or surrounding nervous system targets in the region of the internal jugular vein, such as the carotid sinus nerve and/or associated nerve branches and/or the vagus nerve and/or associated nerve branches. Stimulation energy travels along a conductive bridge that extends from the intravascular lead to the nervous system target, or is relayed from the intravascular lead to another device disposed within or surrounding the target structure.

Description

RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 043,070, filed Apr. 7, 2008, and U.S. Provisional Application No. 61 / 043,350, filed Apr. 7, 2008, each of which is incorporated herein by reference.FIELD OF THE INVENTION[0002]The present invention generally relates to implantable devices and systems, and associated methods for delivering therapy to nervous system targets using components implanted within the vasculature.BACKGROUND OF THE INVENTION[0003]Heart failure (HF) is a condition characterized by reduced cardiac output that triggers neurohormonal activation. This compensatory mechanism functions acutely to increase cardiac output and restore left ventricular (LV) functional capacity such that patients remain asymptomatic. Over time, however, sustained activation of these neurohormonal systems triggers pathologic LV remodeling and end-organ damage that ultimately drives the progression of HF.[0004]In many people, persistent hyp...
